AMH Ovarian Reserve & Fertility Test (B-205)
Understand Your Ovarian Reserve. Make More Informed Fertility Decisions.
Thinking about having a baby, considering egg freezing or exploring fertility treatment? Understanding your ovarian reserve can help you have a clearer conversation about your options.
The AMH Ovarian Reserve & Fertility Test measures Anti-Müllerian Hormone (AMH), an important marker of the small developing follicles within your ovaries. Your result provides information about ovarian reserve and helps guide discussions about fertility treatment, including IVF and egg freezing.
Collect your sample at home using a simple finger-prick blood spot kit. AMH can be measured on any day of your menstrual cycle, so there is no need to wait for Day 3.
What This Test Measures
AMH is a marker of ovarian reserve — the ovarian follicle pool associated with your remaining egg supply.
It is produced by cells surrounding small developing follicles in the ovaries. AMH generally decreases as the follicle pool declines with age.
An AMH measurement can help:
- Assess ovarian reserve in the context of your age.
- Estimate your likely response to ovarian stimulation during IVF or egg freezing.
- Support a wider fertility investigation.
- Provide additional information when investigating possible PCOS.
- Guide discussions about whether further assessment would be useful.
AMH provides information about follicle quantity, rather than egg quality. It does not give an exact egg count or a personal countdown to menopause.
Who Should Consider This Test?
This test may be useful if you:
- Are planning a pregnancy and want to discuss ovarian reserve with your practitioner.
- Are struggling to conceive or undergoing a fertility investigation.
- Are considering IVF, egg freezing or another assisted reproduction treatment.
- Have been advised to check AMH because of your medical or family history.
- Have irregular or absent periods and are having a broader hormone assessment.
- Have suspected or diagnosed PCOS.
- Have concerns about reduced ovarian function.
- Want an AMH measurement without purchasing a larger fertility panel.
How Can an AMH Result Help You?
| Your Situation | How the Result Can Help |
|---|---|
| Planning a family | Adds information about ovarian reserve to discussions involving your age, health and reproductive plans. |
| Considering egg freezing | Helps your fertility specialist estimate the potential response to stimulation and discuss treatment expectations. |
| Preparing for IVF | Contributes to planning ovarian stimulation alongside ultrasound findings and other clinical information. |
| Investigating difficulty conceiving | Provides one part of the assessment, helping distinguish ovarian reserve from other factors affecting conception. |
| Possible PCOS | Higher AMH can reflect an increased number of small follicles and contribute to the wider assessment. |
| Concerns about early ovarian decline | A lower result can prompt a timely discussion about further investigations and available options. |
Understanding Your AMH Result
Lower AMH — Reduced Ovarian Reserve
A lower AMH result may suggest a smaller pool of developing follicles. It can reflect age-related changes or ovarian reserve that is lower than expected for your age.
During fertility treatment, lower AMH may be associated with fewer eggs responding to stimulation.
Low AMH does not mean that natural pregnancy is impossible. It helps inform the next conversation rather than providing a complete answer about fertility.
Higher AMH — A Larger Follicle Pool
Higher AMH may reflect a larger number of small ovarian follicles and a potentially stronger response to fertility medication.
It can also occur in women with PCOS. Where PCOS is suspected, your practitioner will consider menstrual history, symptoms, androgen measurements and other relevant findings.
Higher AMH does not automatically mean better fertility.
AMH Within the Age-Related Range
A result within the laboratory’s age-related range provides context about your ovarian reserve compared with the reference population.
It does not establish egg quality, confirm ovulation or guarantee conception. These involve other aspects of reproductive health.
AMH Reference Ranges
The following age-specific ranges are published by ZRT Laboratory for dried blood spot testing.
| Sex | Age Range | AMH Reference Range |
|---|---|---|
| Women | 18–25 years | 2.59–8.38 ng/mL |
| Women | 26–30 years | 1.70–6.00 ng/mL |
| Women | 31–35 years | 0.81–5.42 ng/mL |
| Women | 36–40 years | 0.24–2.78 ng/mL |
| Women | 41–50 years | 0.06–1.60 ng/mL |
Use the reference range on your own laboratory report when reviewing your result. Age, hormone treatment and your medical history help put the number into context.
AMH, PCOS and Early Menopause
AMH and PCOS
Women with PCOS often have more small ovarian follicles, which can produce a higher AMH result.
AMH can contribute to an appropriate clinical assessment, but a high result alone does not establish PCOS.
AMH and Early Menopause Concerns
Lower AMH can provide information about reduced ovarian reserve. If you have absent or changing periods, hot flushes or concerns about premature ovarian insufficiency, further assessment may include FSH and other investigations.
AMH alone does not diagnose premature ovarian insufficiency or reliably predict when menopause will occur.

Why We Use ZRT Laboratory
ZRT Laboratory is a CLIA-certified diagnostic laboratory based in the USA, specialising in hormone and wellness testing.
Its dried blood spot testing allows you to collect a sample at home without arranging a clinic appointment. The B-205 test measures AMH using ECLIA immunoassay technology.
Would a Broader Fertility Panel Be More Useful?
| Test | What It Measures | Main Purpose |
|---|---|---|
| B-205 — AMH | AMH only | Focused ovarian reserve assessment |
| B-244 — Fertility Basic | AMH, LH, FSH, TSH, prolactin and cortisol | Ovarian reserve plus reproductive signalling, thyroid regulation and cortisol |
| B-245 — Fertility Advanced | Basic markers plus oestradiol, progesterone, testosterone and DHEAS | Broader reproductive hormone assessment |
Choose B-205 when you specifically need an AMH result. If you are investigating irregular periods or several possible hormonal factors, a broader panel may provide more useful information.
B-205 AMH Test — Sample Collection Instructions
Sample type: Dried Blood Spot
View the Full Fertility Sample Collection Instructions
Read all instructions supplied with your kit before starting.
1. Choose Your Collection Day
AMH-only testing can be completed on any day of your menstrual cycle.
If you are collecting samples for additional hormones, follow the timing required for those tests or your practitioner’s advice.
Collect your blood spot sample within one hour of waking, as directed in the fertility kit instructions.
2. Record Medicines and Hormone Treatments
List all medicines, supplements and hormone treatments on your requisition form.
The laboratory’s fertility kit instructions do not recommend testing for individuals using hormonal contraceptive pills, patches, vaginal rings, injections or implants. Testing is permitted with a progestin IUD; record its use.
Do not stop prescribed contraception or hormone treatment without advice from your prescriber.
3. Prepare Three Days Before Collection
Follow the laboratory’s instructions to avoid:
- Biotin / vitamin B7 supplements, including hair and nail formulas.
- Anti-ageing or anti-wrinkle facial creams.
If biotin is prescribed, check with your prescriber before withholding it.
4. Follow Any Hormone-Treatment Instructions
If you use prescribed hormones, continue as directed and follow the preparation guidance in your kit.
| Treatment Type | Laboratory Guidance |
|---|---|
| Topical, swallowed, troche or sublingual hormones | The instructions advise allowing at least 12 hours between an evening dose and morning collection. Oral progesterone may be taken at bedtime. |
| Topical hormones | Use gloves or an applicator for at least two days before collection. Avoid applying hormones to the face, lips or neck. |
| Non-contraceptive patches, rings, pellets or injections | Follow the laboratory’s midway-between-doses guidance; check with your prescriber where the treatment has no clear dosing interval. |
| Hydrocortisone, prednisone or other glucocorticoids | Ask your practitioner about collection timing. |
For topical hormone users, the laboratory also advises changing sheets, pillowcases and towels the night before collection and avoiding surfaces containing hormone residue.
5. Prepare Your Hands and Collection Card
- Stay well hydrated without excessive fluid intake.
- Label the card with your name, collection date and time.
- Wash your hands with soap and warm water.
- Dry them with a clean towel.
- Warm your hands to encourage circulation.
- Open the card without touching the collection paper.
6. Collect Your Blood Spots
- Position the card on a clean, flat surface below waist level.
- Select the middle or ring finger of your non-dominant hand.
- Clean the finger with the alcohol pad and allow it to air dry.
- Use the lancet as instructed.
- Wipe away the first blood drop with sterile gauze.
- Keep your hand below your waist and gently encourage blood flow without excessive squeezing.
- Allow one large drop to fall onto the centre of each circle.
- Apply a dressing when finished.
Each spot should fill as much of the circle as possible and soak through to the back. Do not layer drops, smear the blood or touch the filter paper.
Aim to fill all circles where possible. Several well-formed spots are preferable to many small or poor-quality spots.
7. Dry the Sample
Leave the card open to air dry for at least four hours.
Once completely dry, close the cover and store it in a cool, dry place away from direct sunlight until shipment.
8. Complete the Paperwork and Post
Complete the requisition form, including your medicines, supplements, hormone treatments and collection details.
Place the fully dried card and paperwork inside the kit box. Secure the return packaging and post promptly using the supplied return instructions.
If shipping is delayed beyond 24 hours, freeze the dried sample inside its sample bag, as instructed by the laboratory. Samples must reach the laboratory within 30 days of collection to avoid rejection.
Frequently Asked Questions
When Should I Collect My Sample?
AMH is relatively stable across the menstrual cycle, so you can collect on any cycle day. Follow the kit’s instruction to collect within one hour of waking.
Does AMH Measure Egg Quality?
No. AMH provides information about ovarian reserve, rather than egg quality. Age and other clinical information remain important when discussing reproductive outcomes.
Can AMH Tell Me How Long I Can Wait Before Trying for a Baby?
It can inform a discussion about ovarian reserve, but it cannot reliably define your remaining reproductive window or tell you how long it is safe to delay pregnancy.
Can I Conceive Naturally With Low AMH?
Yes. Natural conception can occur with low AMH. Ovulation, age, sperm factors and other aspects of reproductive health also matter.
Can AMH Be Too High?
Higher AMH can occur with a larger follicle pool or PCOS. It can also indicate a stronger response to ovarian stimulation, which is useful information for a fertility specialist planning treatment.
Can This Test Diagnose Early Menopause?
No. AMH may contribute information about ovarian reserve, but early menopause and premature ovarian insufficiency require a broader assessment.
Is This Test Useful Before Egg Freezing or IVF?
Yes. AMH helps estimate the likely ovarian response to stimulation and is commonly considered alongside age and an ultrasound follicle count.
Does the Price Include the Laboratory Fee?
Yes. The laboratory analysis fee is included. You pay the cost of posting your sample to the laboratory.
How Long Is the Kit Valid?
Use your kit within 12 months of purchase, following any earlier expiry date on the materials. Once collected, your sample must follow the laboratory’s storage and return deadlines.
